mi s'ra'rns MICHAEL M. McINTYRE, OF CLEVELAND, OHIO, ASSIGNOR TO THE PERF- COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO,

To all whom it may concern:

' Be it known that I, MIoI-IAEL M. MoIN- TYRE, a citizen of the United States, residing at Cleveland, in the county of'Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Vehicle-Springs, of which the following is a full, clear, and exact description, reference. being had to the accompanying drawings.

My invention relates to vehicle springs, and has for its object to so construct and connect said springs as to secure ease of riding and permit the longitudinal swaying or movement of the body with respect to the axle without detrimental effect upon the springs, as well as to provide means whereby the members of a multiple spring, that is to say a spring composed of two or more spring members, may be connected in such manner as to permit relative movement of the end portions thereof without interfering withv each other and to permit such relative movement between the spring members as well as relative movement between such spring members and thebody of the vehicle.

A further object of the invention is to provide a form of connection between the ends of double or multiple springs and the hangers of vehicles that will permit of the relative movement of the ends of the component members of such springs with theemployment of relatively short hangers for su porting the ends of said members, combining free movement of the ends of the spring members with compactness of construction.

I accomplish these results by the construction described herein, illustrated in detail in the drawings, and embodied in the claims hereto annexed.

Referring to the drawings, Figure 1 repre-' sents a side elevation of a portion of the vehicle frame showing my invention applied thereto {Fig 2 represents a similar view, showing the manner in which my invention may be applied to a different combination of spring members from that shown in Fig. 1';

Fig. 3 represents an enlarged detailof one of' the double links orshackles by which the ends of the spring members in Fig} are:co11- nected to the vehicle fraine and Fig. 4 a sectional detail of the ClOllblQllllkS or shackles shown in Fig. 2, the portions of the par-ts when the sprin s are deflected being-indicated in dotted ines.

b t 9- re? er. te -5% t its up p A similar pair, sh ft shackles is provided for thehanger the lower ends of the sidelinks of t shackle being pivoted to ,and'be plates. 1 f

Each end of the uppers provided with tlieusual ey ing the chain taut during'tli e' v ing of the body, and to prevent ,tl' turning on a horizontal p'ivot,t ing to move theaxle backa ing as the body is de 'resse necting the spring construction as an entity to the vehicle frame permits this backward and forward movement of the axle relatively to the body, without subjecting the spring ends to any strain other than that to which they would be subjected by the rising and falling of the body. At the same time, owing to the provisionof the short shackle and the manner of supporting the same, the

ends of each spring member are free to elongate or contract, irrespective of the action of the ends of the other spring member.

The construction shown in Fig. 1 is useful in attaching and applying springs to frames having short hangers, as is the case with certain makes of automobiles of recent construction as Well as with other makes of older constructionl In this case, the spring members are preferably the ordinary semi-elliptical spring members, the combined strength of said'members being sufficient to'carry the ve hicle and its lead, and the ends being suflieiently flexible or tender to secure ease of riding.

In the case of frames wherein longer hangers are provided, I may employ the construction shown in Fig. 2, wherein the lower spring member is of the scroll type; that is to say, the ends of the lower spring member are formed into scrolls whielp project through the shorter shackles and are connected at their lower endsto the lower ends of said shorter shackles to the pins or bolts provided for such purpose. In this figure, 4 denotes the upper spring section, and 7 and 8 the hangers. These hangers, as before stated, are considerably lon er than those shown in Fig. 1, and can-accommodate between. the lower ends thereof and the lower surface of the frame 1 shackles having longer side links 10 than is the case with the construc tion shown in Fig. 1. The side links 12 of the shorter shackles are of sufficient length to permit the passage of the scroll 14: between the upper and lower pivot pins or bolts, and to provide sufficient room to accommodate any vertical expansion in said scroll. The l iwer end of the scroll is curved inwardly and connected to the pin or bolt 13% which conmeets the lower ends of the side links 12.

As a means for permitting relative longitudinal movement of the ends of. the spring members and at the same time a bodily movement of the s rings and axle with respect to the vehicle rame and hangers, I consider the hcrcindescribed form of connections between the ends of the spring members and between such members-and the frame to be of great advantage, as it effectively answers the purpose for which it is designed, and accomplishes the same in a particularly compact and effective embodiment.

It will be observed that the ends of the upper spring member are connected to the upper ends of both the short and long shackles,

claim by virtue of the fact that the pin 11 extends through both said shackles.

Having thus described my invention, I claim:

The combination, with the frame and axle of a vehicle, of a pair of spring members secured to said axle, and means for flexibly connecting said members to said frame, said means comprising a hanger projecting from said frame, a link pivote at one end .to said hanger and extending therefrom, a shorter link pivotally connected with the upper portion of the former link, and pivotal connections between the upper end of the long link and the lower end of the shorter link and the adjacent ends of the spring members respectively; substantially as specified.
